FIG. 5 is a flowchart of the main processing of the control program executed by the CPU 1, and FIG. 6 is a flowchart of the key pressing and releasing processing (interruption processing). The control operation of the CPU 1 will be described based on each flowchart. In the following description and flowchart, flags and registers used for control are described by the following labels, and flags and registers and their stored contents are represented by the same label unless otherwise specified.

HARMONY: Flag indicating whether to operate the auto harmony function (1 is "operate")
, 0 represents “do not operate”. ) CHORD: register for storing key release state of accompaniment key range TYPE: register for storing detected chord type ROOT: register for storing root note of detected chord

In the main process of FIG. 5, in step S1,
Reset of various flags ("0" is set in HARMONY flag)
Set), a predetermined dual harmony is set as a default harmony type, and a default type is set, and initialization processing such as clearing in various registers is performed. Next, in step S2, it is determined whether or not the harmony type selection switch 62 is operated, and if there is no operation, the process proceeds to step S5. If there is an operation, all harmony type icons are sequentially displayed on the liquid crystal screen 7 in step S3. To do. At this time, the type name is displayed together with the icon.

Next, in step S4, a harmony selection input process is performed, and the harmony type selected from the icon displayed on the liquid crystal screen 7 is determined as the harmony type to be used in the auto harmony function. In step S4, the user can select a desired harmony type from a group of icons displayed on the liquid crystal screen 7 by operating a predetermined switch or the like.
As a result, the harmony sound during the operation of the auto harmony function is determined based on the selected harmony type.

Next, in step S5, it is determined whether or not the auto harmony switch 61 is operated. If there is no operation, the process proceeds to step S7. If there is an operation, the HAR is performed in step S6.
The contents of the MONY flag are inverted and the process proceeds to step S7.
In step S7, other processing such as tone color setting of the harmony tone, automatic performance processing, and processing corresponding to the operation of various switches is performed, and the process proceeds to step S8. Then, in step S8, it is determined whether or not there is an operation for instructing the end of the main processing. If there is no operation for ending the main processing, step S2
If there is an operation to end the main process, the process ends.

The key release processing of FIG. 6 is started when there is a change in the key release state on the keyboard 5, and first, at step S11, it is determined whether or not HARMONY = 1. HARM
Unless ONY = 1, the operation instruction of the auto harmony function has not been issued, so in step S16, the tone generation process or the mute process according to the key press / release operation is performed and the process ends.
If HARMONY = 1, an operation instruction for the auto harmony function has been issued, so it is determined whether or not the key operated in step S12 is in the accompaniment key range. If the operated key is a key in the accompaniment key range, the contents of the CHORD register are changed in response to the key depression and release in step S13, and a chord is detected from the result. Next, step S1
In step 4, the detected chord type is stored in the TYPE register and the root note is stored in the ROOT register, and the process is terminated.

On the other hand, if the key operated in step S12 is not a key in the accompaniment key range, in step S15, if it is a key depression operation, the pitch of the depressed key, the selected harmony type and detection. The harmony tone is determined based on the chord (TYPE, ROOT), and the harmony tone is generated. When deciding the harmony sound in the process of step S15, the number of harmonies on the low-pitched or high-pitched side of the pitch (original tone) of the currently pressed key is determined based on the selected harmony type. It is determined whether to add a note, and the pitch to be added is selected from the constituent notes of the detected chord and the original note with reference to the decision. Then, in step S16, the sound generation process or the mute process for the original sound is performed by the normal key depression / release process, and the process ends. In step S16, when the original sound is muted, the corresponding harmony sound is also muted at the same time. It should be noted that when the auto harmony function is in operation, the type and root note of the chord are detected from the key release state in the accompaniment key range, but the pronunciation related to the key depression in this accompaniment key range is not executed. As a result, unnecessary sounds are not included in the performance due to the pronunciation of keys pressed in the accompaniment key range.

The present invention is not limited to the above-mentioned embodiment, but can have various modes. Needless to say, the icon corresponding to the harmony type may be other than the example shown in the above-mentioned embodiment as long as the pitch relationship between the original sound (playing sound) and the added harmony sound can be understood. .

Further, instead of the icon, the harmony type may be visually displayed using an LED lamp or the like. For example, the notes (noteheads and stems) shown in Figures 2 and 3
The harmony type is indicated by providing the pattern of the above on the main body panel, providing the LED lamp so that the lighting color can be selected at the notehead, and making the lighting color of this LED lamp different for the original sound and the harmony sound. You can also do so.

Further, the icon of the embodiment shows only whether the harmony sound is added above or below the original sound. For example, whether the harmony sound is added at a pitch position apart from the original sound is shown. For a harmony type that has been determined, its frequency may also be displayed in the icon. The icon may be displayed on the display unit (liquid crystal screen or the like) not only when the harmony type is selected but also when the auto harmony function is operating. Further, by editing the icon, a harmony type suitable for the performer's preference may be created. For example, in the icon of the embodiment, it is possible to shift the positions of black and white noteheads up and down, or to add a new notehead so that a new harmony type can be created.

The chord information is not limited to that input from the keyboard as in the embodiment. For example, chord sequence data in which chord types and roots are recorded as the performance progresses is recorded. The chord may be specified by playing. Also,
In the embodiment, the chord is detected according to the key depression information of the accompaniment key area on the keyboard, but a method of extracting chord information and melody performance information from the entire keyboard may be used.

Further, in the above-described embodiment, the case where the control program and the display data of the icon are recorded in the ROM 2 has been described. However, the control program and the display data of the icon are not recorded in the ROM 2, but the hard disk, the floppy disk, the CD. -The external storage device 4 such as a ROM or MO disk may be used.
